Error Messages

Introduction

HP E4419B User’s Guide 4-3

Errors are retrieved in a ﬁrst in ﬁrst out (FIFO) order. If more than 30

errors occur, the error queue overﬂows and the last error in the queue is

replaced with error -350, “Queue Overflow”. Any time the queue

overﬂows the most recent error is discarded.

Once the errors are read they are removed from the error queue. This

opens a position at the end of the queue for a new error message, if one is

subsequently detected. When all errors have been read from the queue,

further error queries return +0, “No errors”.

To delete all the errors in the queue from the front panel press:

• , , then .

To delete all the errors in the queue remotely use:

• the *CLS (clear status) command.

The error queue is also cleared when the instrument power has been

switched off.
